Every first letter of a word in a title gets capitalized except for articles, prepositions, and conjuntions. "The" is an article, but it gets capitalized here because it's at the start of the title.

I have a slilver cup of metal cup. I have a silver metal cup.

In regular English, you usually put all the adjectives before the object.

I have a slilver cup of metal. I have a silver cup.

Silver is a metal, and most readers know that. Of course, the cup could be made of some other material and have a silver color. That is why I would use the word "metal" later.

I have a sliver cup made of metal. I have a sliver cup made of metal.

I have a slilver cup of metal. I have a silver cup of metal.

This sounds kind of odd to say, but it's technically correct. Although, "a silver metal cup" sounds more natural. We usually put all the adjectives before the noun it modifies.

It is my favorite cup.

Put this in the same sentence as the reason.

It is my favorite cup because it can keep the temperature for a long time. It is my favorite cup because it can keep the temperature for a long time.

The first sentence is a natural way to say this. The second second sentence explains what happens in a more scientific way. The third sentence may be closest to your sentence.

You can't start a sentence with "because." You have other corrections that combine the sentence above with this one, but if you want to keep them as separate sentences, this may be what you're looking for.
